How to Login to Another Website (Not Redirect)

user04

I apologize if this is considered a newbie question, but here goes.

I have a successful login script that works fine. However, I am modifying it so that there are two radio buttons.

1) Login to an Account Info Page (on my server).
2) Login to a Different Page (not on my server...a different website that I am affiliated with).

If the user enters his/her username/password and radio button 1 is selected then they login fine.

If the user enters his/her username/password and radio button 2 is selected then I get stuck.

Do I simply have in the form tag the action attribute link to the login screen of the affiliated page thereby processing the data is if the user was logging in there?

What would the syntax/code look like for this?

Do I need a javascript function running so that if the radio button for the affiliated page is selected that it now changes to a different form? Meaning the form tag's action attribute by default is simply set to "process.php" (on my server). Do I need a completely different form tag where the action attribute is linked to "www.affilatesite.com/process.php" (on their server)?

I hope this makes sense. Any and all help is greatly appreciated.

Thanks

you need to send some info along with the user
when going to next site

this would not be good:
<a href="another_site.php?logged=yes">button</a>
anybody would be able to 'log in'

$_SESSION['loggedin']= TRUE;
header( Location: other_site.php');
will not work, as session variables exist only in one server

I should use setcookie() = logged in
And let the other site test $_COOKIE.
But howto do this practically I do not know, yet.

I guess it does involve some addtional settings,
to define for which domains the cookie is valid
